Question

How to enable button when checkbox clicked in jquery ?

Answer 1

$('input:checkbox').bind('change', function(){
  if($(this).is(':checked'))
     $('input:button').removeAttr('disabled');
});

Answer 2

$("#yourcheckboxid").click(function() {
    var checked_status = this.checked;
    if (checked_status == true) {
       $("#yourbuttonid").removeAttr("disabled");
    } else {
       $("#yourbuttonid").attr("disabled", "disabled");
    }
});

Answer 3

You can do it like this:

$("#checkBoxID").click(function() {
  $("#buttonID").attr("disabled", !this.checked);
});

This enables when checked, and disables again if you uncheck. In jQuery .attr("disabled", bool) takes a boolean, so you can keep this pretty short using the this.checked DOM property of the checkbox.
